Thought i would pass this Tip on ... for another way to resolve temperamental and frustrating hangups / crashing.

My computer is a 64 bit overspec i7 intel platform with all drivers and OS up to date >>> running W8.1.

TC2016 pro platinum would crash all the time ... just building a Fresh Template file with single 2D lines or just altering the UI settings would crash it with a 1 to 10 minute time frame, consistently.

Tried all the known solutions (Reinstall, Repair, Built-in folder) ... Nothing worked to resolve it.

The crash log gave a hint >>> Faulting module path: C;\Windows\SYSTEM32\mfc100.dllThis got me thinking ... Why is the path being directed to SYSTEM 32 ? .... because their is NO file or folder in 32.

So i loaded in the CD of TC and had a read of the READ ME file ... and it states that you can install BOTH TC 32bit and 64bit programs and they will happily run side by side.In fact it also says that installing both versions is the first step to help resolving issues .. (and mine is a show stopper)

So i installed TC 2016 pro plat 32bit ....

Now the stability has improved ... it has created a file with multiple 3D boxes that are stacked n racked and makes the program work hard

It appears to now be stable ... (fingers X)

I would suggest that if your suffering from crashing ... 1: Have a read of the READ ME file with in the TC 2: Install both 32 and 64bit versions of what ever TC version (IE: V21 / 2015 / 2016 / 2017) ... you are using, as i recon it will apply to all3: My theory is that TC 64bit is using a 32bit folder / file.

Can I ask, when you say "Why is the path being directed to SYSTEM 32 ? .... because their is NO file or folder in 32", did you mean no 32 TC files, or that MFC100.dll didn't exist on your computer.

Only reason I ask is that I have loads of MFC files (mostly language files), and the MCF100.dll I have says its a visual studio shared file - file dated 2011 - although I have VS Express installed I also have TC v18 which is 32 bit from 2011.

Although I've had crashes, they were pretty intermittent, (providing I didn't use TC's auto update).

Once this discussion is finished I'll move the thread to the tips and tricks section of the forum.

To answer your question >> did you mean no 32 TC files, or that MFC100.dll didn't exist on your computer.<<Yes >> No 32 TC files

i had NO TC2016 32bit program installed >>> So there was NO file or folder of TC2016 in the 32bit folder side of windows (C:\Program files x86)My thought at the time was that only a 32bit program would utilize the directory SYSTEM32.

Just seeing the path to SYSTEM32 is what led me to open the READ ME file that comes with the install package of TC ... and after reading it .... that gave me the light bulb moment to install TC2016 32bit.

After the install, i fired up TC 32bit and put in the serial key numbers .. Set up a drawing template ...saved it / closed down the programThen fired up TC 64bit and now it is stable.My thought at the time was that the 64bit program could be using some portions of the original 32bit path.

I no nothing about coding, etc ... so the above is just a thought that led to a positive result.

I've had numerous crashes in both 2106 and 2017 and at first I thought it was just me as most of my files are large in size. Sure that in itself is not fundamental reason that tcw 2016 or 2017 platinum should crash at all and I've updated my drivers to the most recent versions available.

What has changed I think is what Mike90RR had discovered and I've now setup, thats installing the 32bit version of tcw2017 platinum and all crashes have now stopped completely, since installing the 32bit version of worked for 5 days straight with no crashes whatsoever and it now appears stable. FWIW, I did have the tcw2016 32bit and 64 bit versions installed together but I still got regular crashes with no ideas as to why. Mostly happening when closing the file and sometimes when working on layer filter changes etc.

To sum up tcw2017 with the 64bit and 32bit installed on the same pc now appears stable, whereas tcw2016 64bit and 32bit installed on the same pc still crash. To clarify I have both 2016 & 2017 32bit and 64bit programs installed on the same pc.

I have not crossed over to TC2016 just yet ... so i can't comment or update on the long term stability of whether TC2016 is finally resolved.I just know that it became stable within the 0 to 10 minute time frame.For me to fully test it ... I have to wait for a simple job to turn up ... so that i can build a Brand New drawing that wont devastate me if the TC2016 plays up. (If it plays up I'll just DWG convert and use my old setup to complete)

Added info about how i run my setup ... It is dedicated to just running CAD.The computer has absolutely no Anti virus installed... All removed. It NEVER sees the internet.No Firewalls and all unnecessary programs have been stopped from running in the background or just deleted.It has been handed over to a Computer Tech and they made sure ALL software and Drivers are of the latest versions.
